Investigation of the rate of photosynthesis

The rate of photosynthesis was increased as the plant’s proximity to the light source increased introduction autotrophs sustain themselves through a process called photosynthesis this is a process by which plants and other specific organisms transform light energy into chemical energy. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, ph and intensity of light the photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. Practical - investigation of factors affecting photosynthesis investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pond weed. Rate of photosynthesis intensity of light as light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor so the rate plateaus at very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph.

This experiment will look at the affect of light intensity on the rate of photosynthesis on elodea plants the rate of photosynthesis is determined by the number of bubbles formed by the elodea plants. This affects the rate of photosynthesis the surrounding temperature room temperature 28°c carry the experiment is held at the biology lab where the temperature are 28°c. The floating leaf disk assay for investigating photosynthesis the problem with et50 is that it goes down as the rate of photosynthesis goes up--it is an inverse relationship and creates the following type of graph (data from steucek, et al 1985): these data are from an demonstration investigation using grape ivy leaf disks minutes.

An investigation into the effect of light intensity on the rate of photosynthesis of canadian pondweed (elodea canadensis) 5 star(s) all green plants need to be able to make their own food. I want to find out if light intensity has any effect on the rate of photosynthesis i want to know if the intensity of light is high, then will the rate of photosynthesis will be faster further investigation is to find out various light intensities and the rate of photosynthesis by using coloured light filters. Photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar photosynthesis occurs in the chloroplast, an organelle in plant cells that contains the molecule chlorophyll chlorophyll absorbs the energy of sunlight. Nuffield foundation » teachers » practical biology » energy » photosynthesis » investigating the light dependent reaction in photosynthesis investigation using the chloroplasts 2 the rate of photosynthesis in intact leaves can be limited by several factors including light, temperature and carbon dioxide which of these factors.

Investigating rates of photosynthesis study play ways to measure the rate of photosynthesis: measure the: amount of oxygen produced rate of co2 uptake rate of increase in plant's dry mass increase in density of leaf discs how is the rate of photosynthesis usually measured. Explain why there is no further increase in the rate of photosynthesis beyond point c fig 22 shows the results from a series of experiments carried out to investigate the effect of light intensity, carbon dioxide concentration and temperature on the rate of photosynthesis. The problem with et50 is that it goes down as the rate of photosynthesis goes up- -it is an inverse relationship and creates the following type of graph (data from steucek, et al 1985).

Effect of colour of light on the rate of photosynthesis 1 effect of colour of light on the rate of photosynthesisintroduction in photosynthesis, plants, some bacteria use the energy from light to produce sugar,which cellular respiration converts into atp. Biology - how light intensity affects the rate of photosynthesis 2110 words | 9 pages biology coursework ¡v does the light intensity affect the rate of photosynthesis the investigation in this experiment i will investigate the affect in which the light intensity will have on a plants photosynthesis process. Investigate the effect of bicarbonate concentration on the rate of photosynthesis in asystasia leaves lucas t background information photosynthesis is the process by which autotrophic organisms use light energy to convert carbon dioxide into sugars as their form of nutrition.

Investigation of the rate of photosynthesis

I and my group all learnt that after an intensive investigation into how the rate of photosynthesis is affected by the amount of light intensity that the higher the light intensity the faster the rate of reaction. Photosynthesis occurred more quickly at the lower temperature when the leaves were at a temperature of 23 o c, the carbon dioxide diminished at a rate of -0079724 ppm/s. This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the canadian pondweed, elodea in the results the pattern is that when the light intensity is higher the readings are generally higher on the graph the less the.

Stage 1 photosynthesis prac this student studied: sace - year 11 - biology the effect of carbon dioxide on photosynthesis photosynthesis is a vital process that autotrophs such as green plants use to convert light energy from the sun into chemical energy.

Investigation 5 photosynthesis what factors affect the rate of photosynthesis in living leaves affect the rate of photosynthesis in plants — both physical variables and biotic variables likewise, students consider variables that might affect the floating disk procedure itself.

Investigating the effect of light intensity on the rate of photosynthesis to investigate the effect of light intensity on the rate of documents similar to investigating the effect of light intensity on the rate of photosynthesis caribbean studies essays uploaded by rosemaryreynolds.

Nuffield foundation » teachers » practical biology » energy » photosynthesis » investigating factors affecting the rate of photosynthesis practical biology a collection of experiments that demonstrate biological concepts and processes. » photosynthesis there are plenty of methods available to measure photosynthesis the method we use is actually a measurement of the carbon dioxide catch: we enclose a small part of the tree inside a chamber and follow the change of co 2 concentration in the air of this chamber. The group knows the chemical process of photosynthesis requires light energy to generate sugar and oxygen(2h2o + co2+light energy = ch2o+o2), if the amount of light shined upon the leaf disks increases then more oxygen would be produced thus allowing the disks to rise at a faster rate (faster photosynthesis rate.
